Fish I.D. is an easier way for a sonar novice to recognize a fishy signal return when he sees it. However, locating fish by symbol only has some limitations.
Your sonar unit's microcomputer is sophisticated, but it can be fooled. It can't distinguish between fish and other suspended objects such as trotlines, turtles, submerged floats, air bubbles, etc. Individual tree limbs extending outward from a group of limbs are the hardest objects for the Fish I.D. feature to distinguish from fish.
To see what's under your boat in maximum detail, we recommend you turn off Fish I.D. and begin learning to interpret fish arches.
You may see Fish I.D. symbols on the screen when actually, there are no fish. The reverse is also true — Fish I.D. can actually miss fish that are present. Does that mean Fish I.D. is broken? No — the feature is simply interpreting sonar returns in a specific way to help take some of the work out of reading the screen. Remember: Fish I.D. is one of the many tools we provide so you can analyze your sonar returns for maximum fish finding information. This and other features can help you successfully "see" beneath the boat under varied water and fishing conditions. So, practice with the unit in both the Fish I.D. mode and without to become more familiar with the feature. This unit's default Fish I.D. setting is off. Fish I.D. is most handy when you're in another part of the boat or performing some task that prevents you from watching the sonar screen. Then, you can turn on Fish I.D. and the audible FISH ALARM. When that lunker swims under your boat, you'll hear it!
Fish I.D. can also be useful when you want to screen out some of the sonar detail gathered by your unit. For example, it can help cut through the clutter of suspended bubbles caused by wave action or boat wakes.
To turn Fish I.D. on, press MENU until the FISH ID menu appears. Press UP ARROW to select ON, then press PWR. To turn it back off, repeat the above steps, but press DOWN ARROW to select OFF.
FISHTRACK™
The FishTrack feature shows the depth of a fish symbol when it appears on the display. To turn it on, press MENU until the FISH ID menu appears. Press UP ARROW to select TRACK ON, then press PWR. To turn it off, repeat the above steps, but press DOWN ARROW to select OFF. (If you want to turn off FishTrack depths but leave Fish I.D. on, press DOWN ARROW to select ON, then press PWR.) Remember, Fish I.D. must be on in order to use the FishTrack feature.
